9 Claims.

- lining and thru the sheet metal garnish frame and are clinched on the inner side of the latter. In order that. these staples may be forced thru the sheet metal it is necessary that a staple of large wire be employed, which is of sufficient strength to enable its prongs to pierce their own holes through the sheet metal.- As a result, two defects are liable 2to occurthe staples either depress the cushioning material on the strip to such an extent as to make the weather seal defective at the points where the staples are driven, or the staples are not depressed into the material far `enough to prevent their engagement with the glass.

The primary object of my invention is to provide a form of lining strip which may be attached to the garnish frame by staples, without depressing the eiective portion of the cushioning material, and which is so constructed that thestaple will be driven in beyond the glass engaging portion of the cushioning material to such an extent that all possibility that the staple will engage the glass is avoided.

Other objects are to reduce the cost of the cushioning lining and make the use of the cushioning shim, which it was found necessary to employ ,in the previous construction, unnecessary, so that a substantial reduction in manufacturing cost may be made without in any degree diminishing the effectiveness of the lining strip.

I accomplish these objects by attaching a cloth covering strip, for the core of the strip, to a fabric lining strip, which is formed so as to produce two cushioning ribs equidistantly spaced from the middle of the core, so that the staples may be driven between the ribs, without disturbing the effectiveness of the latter.

For a. more complete disclosure of my invention, reference is now made to the following specication, in connection with the accompanying drawing in whichz Fig. lis a combined cross sectional and perspective view, on a greatly enlarged scale, of a lining strip embodying a preferred form of my invention.

Fig. 2 is a detail view of a portion of the core.

Fig. 3 is a cross sectional view indicating the method of attachment to the garnish frame.

Fig. 4 is a sectional view at line 4 4 of Fig. 3.

Fig. 5 is a detail view illustrating a preliminary step in the covering operation.

(o1. zas-44.5)

Fig. 6 is a cross sectional view of a modification of theinvention.

As shown in the drawing, the type of metal core which is preferably employed is identical to that disclosed in my said prior patent, which comprises a sheet metal strip having a rolled continuous edge portion a, from which suitable spaced tongues b extend transversely, the end portions of the tongues having oppositely bent portions c vwhich are enclosed in a stainless steel finish bead d, the construction permitting a slight movement of the tongues in the bead to permit bending, to conform to the outline of the window opening.

According to my present invention, I provide a strip e oi' thin but stout cloth and a strip of fabric, which may be plush, felt or cloth with a heavy nap, vand connect said strips by stitches g, which extend along a longitudinal line at a distance from the edge of the strip e and at the middle of the strip f, as indicated in Fig. 5.

Before assembling the strips and core, the latter is passed thru a bath of liquid cement, which is permitted to dry sufliciently to become tacky, and then the cloth strip is wrapped about the core in such a position that its two edge portions extend into the finish bead d and the line of stitches g are held at the middle of the core, at its outer side. 'I'he width of the fabric strip f is substantially greater than the width of the core, and the edge portions of said strip f are placed within the bead d and the rolled edge a, respectively, which latter are clamped thereagainst with suillcient force to hold them securely in this position. As the covering strip e is held in contact with the surface of the core at both sides, the strip f will be gathered in two parallel loop shaped ribs h, which extend lon,- gitudinally of the core, at each side of the middie thereof with their adjacent sides in contact, as shown in Fig. 1.

Before the fabric strip f is attached to the cloth strip e, its back side is preferably rubber impregnated, to give the ribs h the desired stiffness, yet permitting them to yield suillciently to accommodate glass oi' different thicknesses and to provide a suitable cushioning effect for the glass.

When the lining is installed, lining strips are attached to the opposite sides of the window glass channel of the casing, formed for example, by the garnish frame so that theends of each pair of loops on each strip engage one side of the window glass, as indicated in Fig. 3.

In attaching the strip to the garnish frame i staples j are driven through the strip along the line of the stitches g, or between the ribs h, as indicated in' Figs. 3 and 4, the staples being clenched on the inner side of the garnish frame before it is placed in position, so that the strips are securely attached.

As thus arranged the tops of the staples are held at a substantial distance beneath the tops of the cushioning ribs h, so that all possibility that the staples will engage the glass is avoided and at the same time the staples do not to any extent tend to impair the weather seal or cushioning effect of the ribs.

The construction also provides an improved cushioning effect, as compared with that produced by the construction of my said prior patent, and the employment of a shim to reinforce the plush cushioning material' is unnecessary. If, however, a light weight fabric ,f' should be employed, the ribs h may be reinforced by placing a. core 7c within each rib, as shown in Fig. 6. This may be done by extruding rubber within the ribs at the time that the various parts of the lining are assembled.

It is to be noted that the cloth covering g, which is adhesively connected to thev core, has several important functionsz-it not only holds the cushioning fabric in position at the middle of the core, but, when the lining is installed, it is sometimes necessary to cut off the strip at an oblique angle, so that som'e of the tongues of the core are severed from the rolled edge and are only supported at one endby the finish bead d. Under such condition the severed tongues will be held in position by the textile covering which will be adhesively connected to both sides thereof.

I claim:
